Merge tag 'accel-20240426' of https://github.com/philmd/qemu into staging

Accelerators patches

A lot of trivial cleanups and simplifications (moving methods around,
adding/removing #include statements). Most notable changes:

- Rename NEED_CPU_H -> COMPILING_PER_TARGET
- Rename few template headers using the '.h.inc' suffix
- Extract some definitions / declarations into their own header:
- accel/tcg/user-retaddr.h (helper_retaddr)
- include/exec/abi_ptr.h (abi_ptr)
- include/exec/breakpoint.h (CPUBreakpoint, CPUWatchpoint)
- include/exec/mmu-access-type.h (MMUAccessType)
- include/user/tswap-target.h (tswapl, bswaptls)

These inline helpers are all used by target specific code so move them

the API with target specific stuff.

Note we have to include cpu.h in semihosting as it was relying on a
side effect before.
